help
|
|
This option enables sanity checks in s390 low-level entry code.
|
|
Some of these sanity checks may slow down kernel entries and
|
|
exits or otherwise impact performance.

If unsure, say N.

|
|
help
|
|
Enable strict type checking for memory management types like pte_t
|
|
and pmd_t. This generates slightly worse code and should be used
|
|
for debug builds.
|
|
|
|
If unsure, say N.

help

This option provides a debugging facility to inject certain artificial events
|
|
and instruction responses to the CIO layer of Linux kernel. The newly created
|
|
debugfs user-interfaces will be at /sys/kernel/debug/s390/cio/*
